This is an unbelievable fantastically great deal. You get a revision book that shows you how do do the math! It opens up the mathematical body to show you all the GUTS and then explains each piece bit by bit. Don't be afraid or squeamish! For those too frightened to try the exercises, there are fully worked answers at the back.

You also get an advanced scientific calculator. The RedBack is not for the feint heated! It is a finely tuned precision machine - faster and more sleek than a Ferrari, look at it long enough and you might just see a wry smile like that from the Mona Lisa.

The NCEA Maths Power Pack is like a breath of fresh air in a stale and sweaty maths room. Remember Q&A and RedBack users can approach the the NCEA exams with confidence. And only $12 - the people at Mahobe must be mad!
